Terms of use

Version 12 November 2026 (draft)

1. Who we are

Sayfo is provided by [Company name], [address], Chamber of Commerce no. [number], the Netherlands. Contact: [email protected]. This is also our point of contact for users and authorities.

2. What Sayfo is

An app to keep track of your physical books and — if you want — share them with other readers. Sayfo is free to use for up to 50 books. With Sayfo Plus (paid subscription) you get unlimited books and extra features.

3. Age

You must be at least 13. Following, being found and sharing books are available from 16. If you give an incorrect age, we may limit features or delete your account.

4. Your account

You are responsible for your sign-in details. One person per account. You can always delete your account in Settings.

5. Sayfo Plus

• Plus is a monthly or yearly subscription that you buy through the App Store or Google Play. You see the price in the app before you buy.
• The subscription renews automatically unless you cancel at least 24 hours before the end of the period in your App Store or Google Play account settings.
• Payment, cancellation and refunds are handled by Apple or Google under their terms.
• If your Plus ends, all your books and data are kept and you can keep viewing, editing and deleting them. Only adding new books beyond the free limit and the Plus features stop.

6. Your content

Your bookcase, notes and profile remain yours. You only give us permission to store them and show them to the people you choose. Notes and the condition of your copies are never visible to others.

7. Usernames

You choose a username following the rules in the app (up to 2 changes per 30 days). You may not pretend to be someone else, a brand, Sayfo or a staff member. We may change or remove a username or profile text that violates these terms or the community guidelines.

8. Community guidelines

You follow the community guidelines. If you break them, we may hide content, change or hide your profile, or suspend or permanently disable social features. Your own bookcase generally remains usable.

9. Reports, decisions and appeals

You can report profiles and shared books in the app. If we take action against you, you receive a message in the app with the reason, the duration and whether it followed a report. You can appeal free of charge in the app within 6 months. You can also go to a certified out-of-court dispute settlement body or to court.

10. Book data

Titles, covers and descriptions come from public sources (including Open Library, Google Books, national libraries and Wikidata). We do our best but do not guarantee they are correct or complete. You can correct them for yourself.

11. Availability and liability

We aim for a reliable service but do not guarantee the app always works. Export your data if you also want to keep it elsewhere. Our liability is limited to what the law allows.

12. Changes

We will let you know in the app in advance about important changes.

13. Applicable law

Dutch law applies. If you live in another country, you keep the protection your local consumer law gives you.
